Introduction
Mosquitoes are more than just irritating pests in Kenya’s urban centers of Nairobi and Mombasa—they represent a significant public health concern. As vectors for diseases like malaria, dengue fever, and chikungunya, these tiny insects pose outsized risks to residents and visitors alike. The unique climate conditions of Kenya’s two largest cities create ideal breeding grounds for various mosquito species, each with their own habits and health risks.
This comprehensive guide brings together expert knowledge on how to identify the most common mosquito species in Nairobi and Mombasa and provides proven elimination strategies suited to Kenya’s specific environmental conditions. Whether you’re a homeowner, property manager, or business owner, understanding how to effectively combat mosquitoes is essential for creating safer, more comfortable living and working spaces.
Common Mosquito Species in Kenya: Identification Guide
Understanding the enemy is the first step in effective mosquito control. Kenya hosts several mosquito species, but certain ones are more prevalent in urban areas and pose greater health risks.
Anopheles Mosquitoes: The Malaria Vectors
Identification Features:
- Size: 3-6mm in length
- Color: Brown to dark brown
- Posture: Rests with abdomen raised at an angle to the surface
- Wings: Usually have dark and light spots or scales
- Proboscis: Thin and as long as the head and thorax combined
Habitat Preferences:
- Breeds in clean, fresh water with minimal organic matter
- Common breeding sites include rice paddies, slow-moving streams, and temporary rain pools
- In urban areas, can breed in construction sites, neglected swimming pools, and water tanks
Disease Risk:
- Primary vector for malaria parasites (Plasmodium species)
- Most active during dusk and dawn (crepuscular)
- Responsible for approximately 3.5 million clinical malaria cases annually in Kenya
Regional Distribution:
- More prevalent in Mombasa and coastal regions
- Found in lower densities in Nairobi, particularly in peripheral areas with more vegetation
Aedes Aegypti: The Dengue and Chikungunya Vector
Identification Features:
- Size: 4-7mm in length
- Color: Black with distinctive white lyre-shaped markings on thorax
- Legs: White bands or rings on legs
- Wings: Clear without spots
- Behavior: Aggressive daytime biters, especially in early morning and late afternoon
Habitat Preferences:
- Highly adapted to urban environments
- Breeds primarily in artificial containers: flower pots, discarded tires, buckets, bottle caps
- Prefers clean, fresh water
- Eggs can survive dry conditions for months before hatching when water returns
Disease Risk:
- Vector for dengue fever, chikungunya, Zika virus, and yellow fever
- Increasing concern in both Nairobi and Mombasa due to climate change and urbanization
Regional Distribution:
- Historically more common in Mombasa and coastal areas
- Increasingly found in Nairobi as urban development creates more breeding habitats
Culex Mosquitoes: The Nighttime Nuisance
Identification Features:
- Size: 4-10mm in length

- Found in coastal wetlands near Mombasa
Understanding Mosquito Life Cycles and Behavior in Kenya’s Urban Centers
The Four-Stage Life Cycle
- Egg Stage (1-2 days)
- Different laying patterns by species:
- Anopheles: Lays single eggs with floats on water surface
- Aedes: Lays eggs individually on damp surfaces just above water line
- Culex: Lays eggs in rafts of 100-300 directly on water surface
- Eggs can hatch within 1-2 days in Kenya’s warm climate
- Aedes eggs can survive dry conditions for 6+ months
- Different laying patterns by species:
- Larval Stage (5-14 days)
- Commonly called “wrigglers” due to swimming motion
- Feed on microorganisms and organic matter in water
- Must come to surface to breathe (except for Mansonia)
- Development time varies by temperature and food availability
- In Nairobi’s cooler climate: 7-14 days
- In Mombasa’s warmer climate: 5-10 days
- Pupal Stage (2-3 days)
- Known as “tumblers” due to tumbling motion when disturbed
- Non-feeding stage
- Develops adult body parts inside pupal case
- Development faster in warmer temperatures
- Final aquatic stage before emergence
- Adult Stage (2 weeks to 1 month)
- Only females bite and require blood meals for egg development
- Males feed exclusively on plant nectar
- Lifespan affected by temperature, humidity, and predation
- Average lifespan in Kenyan urban environments: 2-4 weeks
Behavioral Patterns in Nairobi vs. Mombasa
Nairobi Mosquito Behavior:
- Seasonal fluctuations with peaks during long rains (March-May) and short rains (October-December)
- Activity reduced during cooler months (June-August)
- Urban heat islands create micro-habitats where mosquitoes remain active year-round
- Average development time longer due to cooler average temperatures
- Higher altitudes (1,795m) generally mean fewer mosquitoes than coastal areas
Mombasa Mosquito Behavior:
- Year-round high activity due to consistent warm temperatures and humidity
- Less pronounced seasonal fluctuations
- Faster development cycles due to higher average temperatures
- Increased vector capacity (more efficient disease transmission)
- Saltwater species present in mangrove areas, presenting unique control challenges
- Higher overall mosquito densities throughout the year

DIY Mosquito Control Solutions Using Locally Available Materials
Homemade Traps and Deterrents
- Plastic Bottle Trap Materials Needed:
- 2-liter plastic soda bottle
- Brown sugar (50g)
- Warm water (200ml)
- Yeast (1g)
Instructions:
- Cut the bottle in half
- Mix brown sugar with warm water until dissolved
- Let cool to room temperature, then add yeast
- Pour mixture into bottom half of bottle
- Invert the top half (minus cap) into the bottom, creating a funnel
- Wrap with dark paper or cloth, leaving top exposed
- Place in shaded area away from outdoor gathering spaces
- Replace solution weekly
How It Works: Yeast produces CO2 which attracts mosquitoes. They enter through the funnel but can’t exit easily.
- Egg Trap for Aedes Mosquitoes Materials Needed:
- Small dark container (old cup or plastic container)
- Rough paper or cloth strip
- Water
- Small amount of grass or leaves
Instructions:
- Line inside of container with rough paper or cloth
- Fill container halfway with water
- Add small amount of dry grass or leaves
- Place in shaded outdoor area
- Check weekly, empty, clean, and replenish
How It Works: Attracts female Aedes mosquitoes to lay eggs on rough surface near water line. Emptying weekly prevents larvae development.
- Neem Oil Spray Materials Needed:
- Cold-pressed neem oil (available in Kenyan health stores)
- Liquid soap (small amount)
- Water
- Spray bottle
Instructions:
- Mix 2 tablespoons neem oil with 1 teaspoon liquid soap

Remember that consistency is key—even small, regular actions can produce significant results in managing these persistent pests.
Frequently Asked Questions
Q: How long after rain should I check my property for mosquito breeding? A: Inspect your property 2-3 days after rainfall. Mosquito eggs can hatch within 24-48 hours in Kenya’s warm climate, so early intervention is crucial.
Q: Are mosquito coils effective and safe to use indoors? A: Mosquito coils provide temporary relief but should only be used in well-ventilated areas. The smoke contains particulates that may cause respiratory irritation with prolonged exposure. Consider alternatives like plugin repellents for indoor use.
Q: How can I protect my water storage tanks from becoming mosquito breeding sites? A: Ensure all water storage containers are tightly covered with lids or fine mesh screening (smaller than 1mm). For larger tanks, consider adding mosquito dunks containing Bti, which is safe for water that will be used for washing but not for drinking water.
Q: Are ultrasonic mosquito repellers effective? A: Scientific evidence does not support the effectiveness of ultrasonic devices for mosquito control. Your resources are better invested in proven methods like screens, repellents, and eliminating breeding sites.
Q: How can I protect my children from mosquitoes at school? A: Apply long-lasting repellent before school, dress them in light-colored clothing covering arms and legs when possible, and advocate for mosquito control measures at school through parent associations. Consider sending repellent wipes for reapplication if permitted by school policy.
